Abstract

Quaternary catchments in the south of the Sorbas Basin, SE Spain have been affected by 2 regionally significant river captures. The river captures were triggered by changes in regional gradients associated with sustained Quaternary uplift in the region. Resulting base-level changes in the affected area reached a maximum of ca. 90 m at the point of capture. The complex evolution of the drainage networks since the base-level change will be traced using a combination of evidence from the geological record (Plio/Pleistocene sediments) and geomorphological record (drainage alignments, degree of incision, and capture cols)
